That is bad news

I like Quetiapine, but I'm not entirely supprised since Olanzapine also causes brain atrophy.

I feel that Quetiapine is a good drug, I wonder if it has this effect even at low doses?

I think that ap's shrink the brain is the false conclusion.

Schizophrenia shrinks the brain.

And they compared first episode schizophrenics on quetiapine with healthy controls...

As far as I know, Antipsychotics decrease the brain shrinkage in shizophrenia. I once read a study comparing first episode schizoprenics on Haldol versus unmedicated schizophrencis. The unmedicated ones hat twice the shrinkage than medicated ones had...

Low doses of quietipine are just a strong antihistamine - doxepin or Phenerganwould do the same thing, and be safer

I have seen 50mg of quetiapine produce a robust antidepressant effect when added to ongoing risperidone treatment. Of course, I don't know why. Perhaps NE reuptake inhibition at low dosages is greater in magnitude than is generally thought. I believe it is the metabolite that is more active.
